Study Flashcards
Target Intensity if VO2 is known
Target VO2(lower end of range)= [(0.40) X (VO2 max- VO2 rest0] + VO2 rest Target VO2 (upper end of range)= [(.89) x (VO2 max- VO2 rest)] VO2 rest
What is HRR
Heart Rate Reserve
the difference between maximal HR and resting HR
Karvonen method:
Target HR (lower end of range)= [(.40) x (HRmax-HRrest)] +HRrest
Target HR(upper end of range)= [(.85) x (HRmax- HRrest)] +HRrest
Muscular Strength vs Muscular Endurance
Strength is defined as one-time maximal force that may be exerted & is localized to a joint or muscle group
Endurance denotes the ability to apply a force repeatedly over time. joint and muscle specific
Program modifications for clients with CVD
- deconditioned and low functional capacity clients may need to stary at low intensities (20-30% HRR or VO2R)
- Target exercise intensity should fall 10-15 bpm below HR that has previously elicited symptoms
- Beta clockers and HR lowering meds can decrease accuracy
- RPE levels of 11-13 typically correspond to the target heart rate for cardiac clients first initiating an exercise program. RPE can be progressed (14-16)
Pregnancy guidelines
use RPE value vs HR, avoid supine position after first trimester, additional 300 more calories,
Diabetes recommendations
3-7/ week, no more than two consecutive days between sessions of aerobic activity because of relatively brief exercise induced improvements in insulin action. avoid exercise during time when hypoglycemic medication is working at its peak. should eat 1-2 hours before exercise
Plyometrics
explosive exercise that targets power dev. stretch shortening cycle where the lengthening or prestretching of skeletal muscles under loading enables a more forceful muscle action
PNF
PNF stretching involves both the stretching and contraction of the targeted muscle group. While there are several ways to employ PNF, the most common technique is termed contract-relax. Following the preliminary passive stretch, the muscles is isometfically contracted for 6 s, relaxed for2-3s, then passively moved into the final stretch which is held for 10-30 s. this method is most effective with the use of a trainer to assist the client through the stretch.
Anaerobic Glycolysis
rapid breakdown of carbs, either glycogen or glucose without oxygen. Produces ATP
Concentric
when sufficient force is produced to overcome the external load and shorten the muscle
Eccentric
production of force occurs when the muscles is lengthening, resisting movement
Isometric
muscle produces force but there is no change in length of muscle

RICE
Rest Ice Compression Elevation
Unit of muscle contraction
sacromere
Right side of the heart
responsible for collecting blood coming from the body and pumping the blood through the lungs
Left side of the heart
collects blood from lungs and pumps it to all parts of the body
Sinoatrial node
(SA) intrinsic pacemaker where most normal electrical impulses originate
AV node
responsible for delaying electrical impulses for .12 sec between atria and ventricles and allows atria to contract and fill ventricles with blood
Order of spinal curves
Cervical, thoracic, lumbar, sacral, coccyx
Kyphosis
convexity of curve is posterior
lordosis
convexity of curve is anterior
DOMS
Delayed onset muscle soreness is a sign that you have done too much too soon. 24-48 hours after session. lasts 5-7 days
hypertrophy
increase in muscle size thought to occur through remodeling of proteins within the muscle cell and an increase of myofibrils
